I never had any ejection problems with the 32 using a scope mounted on the grooved 22 style mount. (old style)In fact the ejection from the 32 is downright violent. It throws brass 30 feet back and to the right. Luckily it clears the shooter on the right if I'm not using a net. I've never used one of Larrys mounts but I don't like the looks of them. This because I had lots of trouble with ejection in my 22. Brass would bounce off the scope and fall in front of the bolt. I cured this by drilling and tapping the receiver behind the ejection port and installing a short weaver base. I tried a mini scope on this but didn't like it so I now use a tube style scope mounted with one ring. This leaves the port clear. I haven't had a single malfunction since doing this.

Larry's mount looks to me to restrict the ejection port even more than using the 22 style rings on the old style grooved receiver. However the ejection from the 32 is so strong that it may be ok. If you get one of the new style guns, you only have two options for scope mounting. Larry's mount or modification of the receiver.

No doubt the .32 Benelli has what could best be described as a violent ejection. The first outdoor match where I shot mine, I had a hard time finding my brass. My 1911 ejects about 5 feet out at 2:00. So out of force of habit, I was looking there. After the CF match I was looking for my brass, and a guy 4 stations to my right asked if I was shooting a .32 long. My brass was 30 feet away at 4:00 to 5:00. I'm using very light charges of powder, and had a new recoil spring to boot. Very accurate little pistol at 25 yards. Still working on a load for 50 yards.

Jon made site mounts which replaced the rear sights on both of my MP90s. I was concerned about the weight and balance (i.e. nose heavy) with Larry's mount. (I have one of his for my 208s and don't really like/use it). I use a Burris FF3 dot sight, under 3oz.
